János Szebeni, MD, PhD, DSc

CEO and Chief Scientist

Dr. János Szebeni, MD, PhD, DSc, Med. Habil., immunologist, co-founder and CEO of SeroScience Ltd. is also director of the Nanomedicine Research and Education Center at Semmelweis University in Budapest and full professor of immune biology at Miskolc University in Miskolc, Hungary. He has held various guest professor and scientific positions in Hungary and the United States where he lived for 22 years. His research on various themes in hematology, membrane biology and immunology resulted in over 150 publications including peer-reviewed papers, book chapters, patents, and a book entitled “The Complement System: Novel Roles in Health and Disease” (Kluwer, 2004). He was primary investigator in more than a dozen European and Hungarian research grants and over 30 CRO projects over the past 10 years. Dr. Szebeni is a regular speaker at international conferences and seminars with over 60 presentations in the past five years. He is also an ad hoc consultant for the United States Food and Drug Administration (FDA). Three fields stand out where he has been most active: artificial blood, liposomes and the complement system. His original work led to the CARPA concept, i.e., that complement activation underlies numerous drug-induced (pseudo)allergic infusion reactions. CARPA has been included in a recent European Medicines Agency (EMA) guideline as a recommended preclinical safety test.

László Rosivall, MD, PhD, DSc


László Rosivall, MD, PhD, DSc, full professor, is co-founder of SeroScience Ltd. Dr. Rosivall is currently head of the International Nephrology Research and Training Center, and the PhD School of Basic Medical Sciences at Semmelweis University. He is former head of Department of Pathophysiology, and has also served as Rector of the Semmelweis University. During his extensive academic and teaching career, among other things, Dr. Rosivall pioneered recognizing and characterizing the intrarenal renin-angiotensin system (RAS). Using nanotechnology he visualized the glomerular filration rate (GFR) in vivo and discovered a new, short loop feedback mechanism in its regulation, which refined fundamental knowledge of several basic renal physiological issues. He is also a Széchény prize laurate.
